Description

The invention relates to machines for the manufacture of nails made of metal with a knife for cutting nail blanks, as well as a stamp and clamping jaws for holding the workpiece during the formation of the head.

In the proposed machine, bending, insertion is performed by a ram in the form of a slider, which feeds the cut piece through a corresponding cut in the matrix wall, made in the form of a pipe, under a stamp to form a head. To actuate all the working bodies of the collet to feed the material, the knife for cutting the workpiece, the slider, the stamp and the clamping jaws are wedge-fists placed on rods pivotally connected to one common lever.

The schematic drawing shows a side view of the machine.

On the table 20, a stand 7 is installed, on top of which a lever 2 is placed. The band metal 18, from which nails are made; served by collet 24 to guide Yu, where, by means of a knife 8; provided with a spring 9 and controlled by a fist 6, a piece of the workpiece is produced. Along the guide box-shaped part 77, the billet enters the opening of the fixed punch body 75, which is designed as a slider 14 controlled by a cam (O71)

squeezed from the body spring. Under the action of the cam 77, the punch 14 longitudinally bends the workpieces and pushes them into the corresponding slot located opposite it in the wall of the matrix made in the form of a tube 76 and installed under the stamp 23. fixed on the rod 4 pivotally connected to the lever 2. The workpiece is folded pushed to the notches 22 of the clamping jaws 19, moved apart by a spring, one of which is fixed and the other is controlled by the fist 7. By hitting the stamp 23, by clamping the work piece in the cheeks 75, a nail head is formed and the last one Cheek 19 spring falls outside. The wedge-shaped cams 6, 7 and 77 controlling the working parts of the machine are placed on rods x 4, 5, 12 pivotally connected to one arm 2. Rods 4 vi 5 pass through guide holes in brackets 3 attached to the stand. The cam 77 is connected by a rod 75 sliding in 7 clips attached to the stand, with a collet 2, hingedly connected to a part 25, a carrier protrusion 26 and intended for feeding material. When raising the cam 77, the protrusion 26 fits under the spring arm 27 and the portion 25 presses against the fixed cam. the collet 2 and captures the tape material, which is pulled down when the fist is lowered // until the crimp 26 is released from the lever 27, after which the collet releases the tape. .

The subject matter of the invention.

1. A machine for making nails from a band metal using a knife for cutting nail blanks, as well as a stamp and clamping jaws for holding the billet during the formation of the head, characterized in that a slider 14 is used to feed the cut pieces blanks under the stamp 23 for about-f development of the head, and the matrix is located; The tube 16, which is false under the stamp 23, is opposed to the slider / - corresponding to its slot in its wall.

2. In the use of wedge fists described in paragraph 1 of CTaHKej, b, 7, 77; on rods 4, 5, 12, 13, reinforced in an appropriate number and order on one common lever 2, which serves to actuate all workers: machine organs, namely, material feed collets, knife §-for cutting blanks, a slider 14 , the stamp 23 and the movable clamp for the workpiece cheeks 19.
